A high precision Q-meter for the measurement of proton polarization in polarised targets

A Q-meter system for the measurement of the proton polarisation in polarised targets is described, in which the real part of the output signal, rather than its magnitude, is used to obtain the polarisation. It uses a radio frequency phase sensitive detection technique. Calculations are presented whi...

Summary:A Q-meter system for the measurement of the proton polarisation in polarised targets is described, in which the real part of the output signal, rather than its magnitude, is used to obtain the polarisation. It uses a radio frequency phase sensitive detection technique. Calculations are presented which show that a very high linearity is obtained with this system when used under the experimental conditions obtained in typical polarised targets. A description of the electronic circuits used to implement such a system is given, together with measurements of their performance.
